Introduction
A survey is a systematic snapshot that is used to infer a larger whole. Surveys have
been used throughout the years in a variety of forms. In this assignment, we will be using the
survey to compare the expenses of the residents in Klang Valley and Malacca on their
methods of transportation.
The data collected from the survey will be analysed, using the quantitative studies
including bar charts, pie charts or graphs to examine the variables and consistency of
personal or public transportation users in Klang Valley and Malacca.
Statistics means a quantitative data on any subject, especially data comparing the
distribution of some quantities for different subclasses of the population. To ensure that the
data collection is undertaken in a way that allows valid conclusions to be drawn, we have
been put into groups that consist of four to five members with the purpose of collecting,
organizing, presenting and drawing a conclusion for this statistical data.
On the other hand, data analysis is information organized for analysis or used to
reason or make decisions. Data analysis has multiple sides and approaches, surrounding
diverse techniques under a variety of names in different business, science and social
science domains.

Purpose of the Survey
The purpose of our survey is to study the expenses on car of residents from
two different geographical regions which are Malacca and Klang Valley. For those
residents who own cars, we identified their spending behavior such as how much
money they spent on purchasing their respective cars, expenses on petrol per month
and their car maintenance fees. For those who modified their cars, we also identified
how much they spent on modifying their cars.On the other hand, for those who do
not own a car, we identified how much they spend on transportations.

Methodology
1. Malacca
From 25th to 27th October, Esther Lim, Tan Zi Cin, Lim Chong Min and Sharon
Chow went to Malaccafor 3 days 2 nights for a study trip. During our stay
there we conducted the survey at Aeon Malacca and Dataran Pahlawan. We
approached Malacca residents at the malls and asked them to fill up our
survey forms

TeohHui Yu and Hong Sang Won couldn’t make it with us to Malacca so they were in
charge of conducting the surveys in the Klang Valley region. They conducted the
survey in GM Klang and Sunway Pyramid. They conducted the surveys on 25th and
26th October.

Conclusion
After conducting the survey and doing the calculations, we got to learn the
spending behaviors of Klang Valley and Malacca on cars and for those who do not
own cars, we got to learn about their spending behaviors on transportations. 43 out
of 50 Klang Valley residents that we surveyed own cars and 35 out of 50 Malacca
residents that we surveyed own cars.
For purchasing a car, the mean of amount of money spent by Klang Valley
residents is RM55000.38 which is less than the mean of amount of money spent by
Malacca residents on car, RM 65286.21.Even though the modal class of amount of
money spent by Klang Valley residents is 60001-70000 while Malacca is lower with
modal class 40001-50000 and there are less people in Malacca who owns car
compared to Klang Valley. This means those who own a car in Malacca tend to
spend more on purchasing compared to Klang Valley. This may be because those
who could afford purchasing a car in Malacca are more financial capable compared
to Klang Valley.
For car loan 40 out of 50 Klang Valley residents that we surveyed got a loan in
order to purchase a car. The mean of the monthly installment they pay is RM 813.
On the other hand, 29 out of 50 Malacca residents that we surveyed got a loan in
order to purchase a car. The mean of the monthly installment they pay is RM 957.4
which is higher than Malacca. There are less people in Malacca compared to Klang
Valley who got loans in order to purchase a car. This could be because the Malacca
residents who own cars are capable to pay for their car in one go compared to Klang
Valley residents who got car loans and pay high monthly installments.

For petrol, the mean of amount spent by Klang Valley residents is RM250.50 and
for Malacca residents is RM190.50. This shows that Klang Valley residents tend to
spend more than Melaka residents in petrol. The obvious reason for this event would
be the driving distance of Klang Valley residents is further compared to Malacca
residents.
For car modifying, 7 out of 43 Klang Valley residents who own cars modified their
cars while 5 out of 35 Malacca residents who own cars modified their cars. The
mean of amount of money spent on car modifying by Klang Valley residents is RM
750.50 and Malacca residents is RM 950.50. Malacca residents tend to spend more
in modifying their cars compared to Klang Valley residents. One obvious reason
would be most Klang Valley residents bought cars in order to drive themselves from
places to places especially for work proposes while Malacca residents see driving
and car modifying as activities that they do to kill their free time.
For car maintenance, the mean amount of money spent by Klang Valley resident
is RM192.36, for Malacca resident is RM196.04. When it comes to car maintenance,
there isn’t much difference for these two places, probably because residents of both
places prioritize road safety.

On the other hand, there are 7 out of 50 Klang Valley residents and 15 out of 50
Malacca residents that we surveyed do not own cars. The mean amount of money
for Klang Valley residents on transportation is RM61.21 and Malacca is RM92.17.
Klang Valley residents tend to spend less in transportation than Malacca residents
because compared to Malacca, Klang Valley has a greater diverse of public
transport that comes with an affordable price tags. In Malacca, the choices are
limited.
In conclusion, more Klang Valley residents tend to own cars, spend more in petrol
and pay more of monthly installment compared to Malacca residents. Though less
Malacca residents own cars but for those who do, they tend to spend more in
purchasing a car, has lower tendency to get a loan and pay more for both car
modifying and maintenance. This shows that those who own cars in Malacca tend to
be more financial capable compared to those in Klang Valley. For those who do not
own cars, Klang Valley residents spend less in transportations compared to Malacca
residents because there are more and cheaper public transport options in Klang
Valley compared to Malacca such as monorail and LRT.
